When I view the profile of someone and his tags, I can see what the profile is tagged with and in list view also how often. If I click on the tag in both views it starts a search for this tag. This makes sense in cloud view but in the list view I would much more expect and like if a click on the tag would add my vote for this tag on this profile, increasing the number. This way one can scroll down even a long list of tags and add those one agrees with. Otherwise it is a lot of scrolling down the tag list, getting inspiration, scrolling back up to the input box, typing everything in, scrolling down to the position you left off.
